IMPROVEMENT IN PLAITING MACHINES. n

Specification forming part of Letters Patent No. 181,480, dated August 22, 1876; application filed May 10, 1876.

ing-Machincs and we do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

. The nature of our invention consists in the construction and arrangement of a plaitingmachine, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a side elevation, Fig. 2 a longitudinal section, and Fig. 3 a plan view, of our invention. Fig. 4 shows the fabric.

A represents the box or frame of our machine, provided with the bed B, over which passes the endless apron C, said apron passing around a large roller, D, at theinner end of the bed, and around a small roller, a, at Over the inner end of the bed B is a large pressure-roller, E, having its journal-bearings-in suitable posts or standards attached to the box or frame A. Under this roller, on top of the apronO, is a series of wires, 1) b, the inner ends of which are attached to a cross-bar, d, in the frame,

and the outer ends secured to a frame, G,-

which is hinged to the sides of the box, and held down'by spring-catches f f. These wires 1) hold the cloth after it is plaited.

At the inner end of the bed is an inclined plate, H, projecting in between the rollers D and E, upon which plate the cloth is laid, and the plaits formed by the moving of the tuckerplate I. This plate is composed of one or more springs, h, at its inner or front edge, for the purpose of fitting uneven cloths. The plate I is, by a rod, k, connected With an arm, m, on a shaft, 12, which has a handle, J, on its end, for operating the machine. This handle is, by a rod, 10, connected with a lever, L, pivoted on the journal of the roller D, and carries a pawl, s, to engage in a toothed wheel, P, on said roller-journal. The two rollers D E are geared together by two cog-Wheels, R R.

The handle J is moved back and forth, giving the plate I a reciprocating and therollers and apron an intermittently rotary motion. As the tucker-plate I moves backward, the pawl 8 takes hold in the wheel P, and rotates the roller D, thereby feeding the cloth forward; and when the plate 1 moves forward the rollers and apron are stationary, the upper roller .E holding the cloth, so that the springs 71. of

the tuckerplate can take hold of the same and lay the plait. The rollers layand press the plaits as they pass between said rollers.

Either one of these rollers may be heated by any suitable means, so as to press the plaits properly; and, to obviate the necessity of basting before sewing the plaited material on the dress, adhesive strips it may be passed in under the rollers on the goods, and be pressed down onto the same.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is Y 1. The endless apron G, in combination with the rollers D, E, and a, and the tucking-plate I, substantially as and for the purposes herein set forth.

2. The wires b b, or their equivalents. passing between the rollers D-E, their inner ends attached to a stationary bar, and their outer ends to a pivoted frame, as herein set forth.

v3. The combination of the endless apron O, rollers D a, pressure-roller E, wires 1), inclined plate H, and the tucker-plate I, all constructed and arranged to operate substantially as and for the purposes herein set forth.

4.. The adhesive strips t, in combination with aplaiting-machine, for the purposes herein set forth.

In testimony that we claim the foregoing as our own we affix oursignatures in presence of two witnesses. 4
